Replacing a grill grate should be simple, but the 18-inch label hides a trap. A grate sold to fit an 18-inch kettle often measures 17 and a half inches because it has to drop inside the bowl, and a grate sold for a gas grill is a different shape entirely. Get the number wrong and it rattles or will not seat. We matched each grate to the frame it claims to fit, then cooked on it to feel the difference between plated steel and cast iron. Steel heats fast and is easy to live with, while cast iron holds heat and lays down deeper sear marks but demands seasoning. Hinged grates earn their keep on long charcoal cooks, since flipping up a side lets you feed in fresh coals without pulling everything off. The right grate seats flush, survives the heat without warping, and matches how you actually cook rather than just the size printed on the box.

Key buying factors
Measure your existing grate, not the grill model name. An 18-inch kettle usually takes a 17.5-inch grate that drops inside the bowl, and a half inch off means it rattles.
Plated steel heats quickly and needs no seasoning. Cast iron holds heat longer and sears harder but rusts if you skip the oil-and-dry routine.
Hinged grates flip up at the edges so you can add charcoal mid-cook without lifting food. Worth it for low-and-slow sessions that outlast one load of coals.
Tighter bar spacing keeps smaller foods from falling through. Check the gap if you grill vegetables, shrimp, or fish rather than just burgers.
Thin grates can bow under high heat and never sit flat again. Heavier-gauge steel and cast iron stay flat, which matters for even contact and clean sear lines.
Types explained
Chrome or nickel-plated steel rod, the standard kettle replacement.
Best for: Everyday charcoal grillers who want fast heat-up and zero seasoning maintenance.Heavy iron that stores heat and lays down deep sear marks.
Best for: Steak and burger cooks who chase restaurant-style char and do not mind seasoning.Steel grate with flip-up sides for adding fuel mid-cook.
Best for: Low-and-slow sessions where you need to refuel without disturbing the food.Rectangular grates sized for specific multi-burner gas frames.
Best for: Owners of gas units like the Charbroil Performance series needing an exact-fit swap.Care & usage tips
Run the grill hot for ten minutes after cooking, then brush the grate clean. Carbonized residue lifts off easily when hot and welds on if left to cool.
Wipe cast iron with a thin coat of high-smoke-point oil and heat it until it stops smoking. A built-up seasoning layer is what keeps food from sticking and rust at bay.
After any wet cleaning, heat plated steel dry before storing. Trapped water finds chips in the plating and starts rust that spreads under the coating.
The size on the box describes the grill, not the grate, so an 18-inch kettle almost always takes a 17.5-inch grate that nests inside the bowl rather than spanning the full rim.
Measure your old grate edge to edge before ordering, because matching the actual diameter beats trusting the grill model name and saves you a return.
Frequently asked questions
Why is an 18-inch grate actually 17.5 inches?+
Because it drops inside the kettle bowl rather than spanning the rim. The grill is 18 inches across, but the grate must be slightly smaller to nest flat inside it.
Cast iron or plated steel?+
Plated steel heats fast and needs no upkeep. Cast iron holds heat and sears harder but rusts if you skip seasoning. Choose by how much char you chase.
Are hinged grates worth it?+
If you do long charcoal cooks, yes. Flipping up a side lets you add coals without lifting the food, which is a real convenience on low-and-slow sessions.
Will a kettle grate fit my gas grill?+
No. Gas grills use rectangular grates sized to specific burner frames. Match the part to your exact gas model rather than a round charcoal grate.
